SPECIFICATION forming part. of Letters Patent No. 280,101, dated June 26, 1883.

Application filed February 5.1 883. (No model.) I

- a citizen of the United States, residing at Bos- V hicle is suddenly started or stopped.

ton, in. the county of Suffolk and State of Massachusetts, have invented certain new and use ful Innprovements in Carriage-Lamps; and I do hereby declare that the same are fully described in the followin specification and illusstrated in the accompanying drawings.

This invention relates to that class of vehicle-lighting apparatus in which a candle is pressed upwardly as it burns by a spring bc neath it, so as to keep the flame at one unii'orm point.

The especial object of my improvements is to prevent the slopping of the melted wax or tallow in the top of the candle when the ve- To this end I. form an inward-turned barrier at the extreme top of the cap which. surrounds the candle, such barrier being a portion of the cap extending from all sides toward the flame to'inclose and partially cover the melted wax. I also support the bottom of the candle on the flaring rim of a cup secured within the top coil of the spring, leaving the cup itself vacant until the candle is consumed to the last quarter inch or so, when the wax softens, drops into the cup, into which itis forced by the upward pressure of the spring and the resistance of an inward bead in the tubular cap. This action brings the flaring margin of the cup into contact with the inward bead and prevents any drip or slop.

Candlesticks have heretofore been made with a terminal cap flaring outwardly above the top of the candle, and also having double walls at that point, with an annular recess between them, to receive, from beneath, the vertical sides of a cup which the base of the candle has occupied. Such prior devices do not sep arately or together embody the peculiar features of my invention as recited in the appended claims, since they do not effectually prevent spilling the melted wax.

The drawings show, in Figure 1, a view of a carriage-1amp provided with my improvements. Figs. 2 and 3 are enlarged detail views, showing, respectively, the positions of the parts while thecandle is burning and after it is consumed.

The lamp A has a stem, B, which receives a spiral spring, (1, serving to press upwardly a candle, D, which rests upon the flaring upper edges, c, of a cup, 11,-seated within and secured to the topmost coil of said spring. A

sanvas bag or other mu'l'tler, F, is employed to prevent the spring from rattling in the stem'B. The upper end of the candle bears against the inward bead, G, formed near the top of the cap H, as shown in Fig. 2, the pressure of the spring keeping the candle top at that height as it burns. The natural concavity formed in the top of the candle by the heatcontains a portion of melted wax, and

this is kept from being spilled in sudden stops or startings of the vehicle by means of the inward-turned.barrier I, formed integral with the cap at its extreme upper end. The cap is spun up from a flat disk of sheet metal in a manner well known, and when its center has been cut out to form the flame-opening the horizontal barrier I is the only portion of such disk which has not been reshaped in the formation of the cap. Below the bead Gthe cap is cylindrical for some distance, and then flares outwardly in a graceful curve to meet the re fleeting-surface L of the bottom of the lampchamber, in which it is seated. A tube, K, soldered within the cap, is secured to the stem B by a bayonet-j oint or equivalent connection.

The cup E supports theeandle, while burning, by its edges 6, Fig. 2. At the moment when it is consumed and the flame expires, the

' upward pressure of the spring and the bevel of the inward bead, G, combine to press the softened remnant into the cup, bringing the edges 0 into close contactwith the bead G, as in Fig. 3, so that the wax cannot be spilled down into the stem B or along the spring (l.
